Abstract
Description
Die Erfindung betrifft eine Aufblasvorrichtung für einen aufblasbaren Sicherheitsgurt mit den Merkmalen des Oberbegriffs von Anspruch 1.The invention relates to an inflatable device for an inflatable safety belt with the features of the preamble of claim 1.
Eine gattungsbildende Aufblasvorrichtung nach dem Oberbegriff von Anspruch 1 ist z. B. aus der
Ein grundsätzlich zu lösendes Problem einer solchen Aufblasvorrichtung ist es, dass die Aufblasvorrichtung für den Transport und die Lagerung schubneutral ausgelegt werden muss. Die Aufblasvorrichtung muss dazu so ausgelegt werden, dass die bei einer unbeabsichtigten Aktivierung der Aufblasvorrichtung wirkenden Reaktionskräfte soweit ausgeglichen werden, dass die Aufblasvorrichtung dabei selbst keine schlagartig beschleunigte Bewegung ausführt.A problem to be solved in principle of such an inflator is that the inflator must be designed to be push-neutral for transport and storage. The inflator must be designed so that the reaction forces acting on an inadvertent activation of the inflator are compensated so far that the inflator itself does not perform a sudden accelerated movement.
Aufgabe der Erfindung ist es, eine Aufblasvorrichtung für einen aufblasbaren Sicherheitsgurt zu schaffen, welche für den Transport und die Lagerung schubneutral ausgelegt ist, ohne dass dadurch die Aufblascharakteristik des Sicherheitsgurtes nachteilig verändert wird.The object of the invention is to provide an inflator for an inflatable seat belt, which is designed for the transport and storage thrust neutral, without thereby the inflation characteristics of the seat belt is adversely affected.
Gemäß dem Grundgedanken der Erfindung wird vorgeschlagen, dass die Aufblaseinrichtung einen schwenkbaren Deflektor aufweist, welcher aus einer Transportstellung in eine Aktivstellung verschwenkbar ist, wobei der Deflektor in der Transportstellung in den austretenden Gasstrom hineinragt, und in der Aktivstellung in eine den austretenden Gasstrom freigebende Stellung verschwenkt ist.According to the basic idea of the invention, it is proposed that the inflator has a pivotable deflector, which can be pivoted from a transport position into an active position, the deflector protruding into the outflowing gas flow in the transport position, and in the active position pivoted into a position releasing the exiting gas stream is.
Aufgrund des erfindungsgemäß vorgesehenen verschwenkbaren Deflektors wird der Gasstrom in der Transportstellung des Deflektors bei einer unbeabsichtigten Aktivierung des Gasgenerators an dem Deflektor soweit umgelenkt, dass sich die auf die Aufblasvorrichtung wirkenden Reaktionskräfte des austretenden Gasstromes und die auf den Deflektor wirkenden Reaktionskräfte im Idealfall gegenseitig aufheben, so dass dabei auf die Aufblasvorrichtung selbst keine oder nur sehr geringe Kräfte wirken, und die Aufblasvorrichtung insgesamt bei einem in der Transportstellung befindlichen Deflektor als schubneutral angesehen werden kann.Because of the pivotable deflector provided according to the invention, the gas flow in the transport position of the deflector is deflected at an unintentional activation of the gas generator to the deflector so far that cancel the acting on the inflator reaction forces of the exiting gas stream and acting on the deflector reaction forces ideally, so that thereby act on the inflator itself no or only very small forces, and the inflator can be considered as thrust neutral overall at a deflector located in the transport position.
Nach der Montage bzw. zur Montage der Aufblasvorrichtung an dem Kraftfahrzeug wird der Deflektor durch die montierende Person aus der Transportstellung in die Aktivstellung verschwenkt. Bei einer nachfolgenden beabsichtigten Aktivierung des Gasgenerators im Unfall wird der von dem Gasgenerator erzeugte Gasstrom von dem Deflektor dann nicht mehr umgelenkt und stattdessen ungehindert auf die Lage des Sicherheitsgurtes geleitet. Der Sicherheitsgurt kann in dieser Stellung des Deflektors ohne Verluste des Gasstromes und insbesondere mit dem größtmöglichen Volumenstrom und der größtmöglichen kinetischen Energie des Gasstromes aufgeblasen werden. Der Deflektor hat damit in der Aktivstellung keinen nachteiligen Einfluss auf das Aufblasverhalten des Sicherheitsgurtes.After assembly or installation of the inflator on the motor vehicle of the deflector is pivoted by the person assembling from the transport position to the active position. In a subsequent intended activation of the gas generator in the accident, the gas flow generated by the gas generator is then no longer deflected by the deflector and instead passed unhindered on the position of the seat belt. The safety belt can be inflated in this position of the deflector without loss of gas flow and in particular with the largest possible volume flow and the maximum kinetic energy of the gas flow. The deflector has thus in the active position no adverse effect on the inflation of the seat belt.
